Abstract
The objective of this research was to select parents and hybrids that would constitute a suitable initial population to develop new forage pea varieties with high herbage and seed yields suitable for the Thrace Region in Edirne province. Furthermore, the aim was to develop a forage pea breeding program suitable for the region by investigating the genetic structure of the divergence generation of hybrid compatibility. Three-line (Drujba, Gölyazı, M65) and six tester (Kurtbey, Taşkent, Mir, Kirazlı, Naota, Pleven10) parents were used as the hybrids and rootstocks as material using the Line x Tester analysis method. The study was conducted under field conditions at the Thrace Agricultural Research Institute using a randomized complete block design with three replications. In the study, measurements, counting, weighing, and analysis were conducted for plant height, biological yield, number of pods per plant, number of seeds per pod, number of seeds per plant, seed yield, and 1000-seed weight. Statistical analysis was conducted using R. For the traits studied, general and specific compatibility abilities, heterosis and heterobeltiosis values, and broad and narrow-sense heritability were determined for the parents and F1 generations using line x tester analysis. In conclusion, there is sufficient genetic variation in the studied population for the yield components. Non-additive gene effects were detected for all traits studied in the F1 generation.
